Visual Framework
Indicates if an item has been bookmarked to a list of favourites or similar. Use vf-button instead of this component for the main call to action on a page.
This component shows if a piece of content has been selected by a user as a favourite using a text label and icon.
No JavaScript functionality is provided and it is expected that the state handling will be done on a case-by-case basis on the project application.
Use vf-button instead of this component for the main call to action on a page.
The active state of the icon is managed by adding the class vf-bookmark--active. This class should be added by your framework or sever-side code.
The component can be configured with a number of options.
bookmark_href: defaults to JavaScript:Void(0);
label_inactive: defaults to Bookmarklabel_active: defaults to Bookmarkedis_active: defaults to true
true or falsevf-bookmark--active CSS classlabel_inactive or label_activemodifier: defaults to inline
inline or buttonicon: defaults to heartThis component targets WCAG 2.1 AA accessibility.
Note that the SVG icons use aria-hidden="true" as to be ignored by screen readers.
The EMBL-EBI Training site includes pages that use the inline variant to mark a training course as favourite and a customised version of the button variant to mark a page as complete.
Depending on your environment you'll want to use render or include. As a rule of thumb: server-side use include, precompiled browser use render. If you're using vf-eleventy you should use include.
includeYou'll need to pass a context object from your code or Yaml file (example), as well as the path to the Nunjucks template. Nunjucks' include is an abstraction of render and provides some additional portability.
{% set context fromYourYamlFile %}

{% set context = {
"component-type" : "element",
"bookmark_href" : "JavaScript:Void(0);",
"label_inactive" : "Add as bookmark",

"modifier" : "button",
"icon" : "heart",

{% include "../path_to/vf-bookmark/vf-bookmark.njk" %}
renderThis approach is best for bare-bones Nunjucks environments, such as precompiled templates with the Nunjucks slim runtime where include is not be available.
